6000 Series Discrete Input/Output Modules
-6050 Digital Input/Output Module
2. Pin Assignment
NuDAM-6050 is a digital input and output module. The
digital input channels can monitor active TTL signals, and
sense passive switch on/off signal because of the internal pull
high resistors. The convenient open collector output channels
can sink up to 50mA current. Combining with the relay
devices, it is possible to control the high power devices by
programming output channel of the NuDAM-6050.

1.
Configure every single NuDAM module under the
administration utility.
2.
The baud rate setting and calibration procedure
must be done under the DEFAULT* mode.
3.
The baud rate and check-sum status must be identity
with the application network. The address ID must
not be conflict with other modules on the network.
4.
Plug the new module to the existing network.
5.
Use the NuDAM administration utility to check the
entire network.

*The module is in DEFAULT mode when DEFAULT* pin
connected to GND while applying power on the module.
*Do not apply any power signal to DEFAULT* pin, just left
it open or connected it to GND.

6. Command Set
There are three categories of NuDAM commands. The first
is the general commands, including set configuration
command, read configuration, reset, read module‘s name or
firmware version, etc. Every NuDAM can response to the
general commands. The second is the functional commands,
which depends on functions of each module. Not every
module can execute all function commands. The third is the
special commands including functions about the
programmable watchdog timer, safe values, and the
programmable leading code. All the commands used in the
NuDAM discrete input/output module are list in the following
table.
